NECK-YOKE COUPLING.

SPECIFICATION forming part of Letters Patent No. 391,048, dated October 16, 1888.

' Application filed May 7, 1888. Serial No. 273,130.

(No model.)

T0 (1% whom it may concern:

Be it known that 1, JOHN JACOB HENZIE, Jr. of Deep River, in the county of Poweshiek and State of Iowa, have invented a new and useful Improvementin Neck-Yoke Coupling for OarriageTongues; and I do hereby declare that the same is fully described in the following specification and represented in the accompanying drawings, of which- Figure l is a side view of the neck-yoke in position. Fig. 2 is a top view of tongue with ferrule. Fig. 3 is a bottom view of the socketclevis for the tongue; and Fig. 4 is a view of the plates for covering the center of the neckyoke.

The object of my invention is to make an improved neck-yoke coupling in which it is impossible for the yoke to bind or catch in any position, and also in which it is less liable to catch into or through fences, hitching-poles, 850., causing breakage.

A is the tongue, on the end of which is the ferrule B. The ferruleis provided with a collar, C, near its inner end, which extends nearly around the said ferrule, leaving an open space, D, which is on top side of the pole, the object of which will be explained farther on.

E is a socket-clevis which fits on the ferrule, and is provided on its inner and under side with a lug, F, that projects beyond the end of the socket-clevis. This lug has a recess, G, into which the collar 0 fits. The clevis is formed by the arms H H, which project from the end of the socket, both arms being perforated to receive the pivots I I, formed on the yoke-plates K K, which are formed in two pieces, in which is inserted the yoke L. The

plates K K are concave and are fastened to the yoke by the bolts M M through holes in each end. The plates are first placed in the clevis by inserting the logs in the holes in the arms. The edges of the plates are then brought together, when the yoke is inserted and the bolts passed through the plates and yoke. This keeps the plates and socket-clevis connected to the yoke.

To detach the yoke from the pole, turn it over, which will bring the lug opposite the opening in the collar on the socket, when the socket can be pulled from the pole with the yoke. The yoke is replaced in the same manner by turning the under side up and pushing on the socket until the lug passes through the opening in the collar, when the yoke is-turned over and again becomes fastened to the pole.

Having thus described my invention, what I c'aim is as follows:

1. In a neck-yoke, the combination of a carriage-tongue and a ferrule provided with a collar, partly encircling the ferrule,with a socketclevis provided with a recessed lug and the yoke, substantially as shown and described.

2. In a neck-yoke, the combination of the ferrule provided with a collar, extending partly around said ferrule, with the socket-clevis provided with a recessed lug for engaging the collar, the perforated arms,and the plates pro vided with the lugs, substantially as shown and described.

3. In a neck-yoke, the combination of the socket-clevis with the plates provided with pivots, and the yoke, substantially as shown and described.

4.. In a neck-yoke, the combination of the socket-clevis with the plates provided with the pivots, the yoke, and the fastening bolts, substantially as shown and described.
